UNSPSC 41181522: Properdin factor b immunological test system

In this classification, a Properdin factor b immunological test system is a device that consists of the reagents used to identify by immunochemical techniques Properdin factor b. US FDA regulates Properdin factor b immunological test system under 21 CFR 866.5320 and under FDA product code JZH.

UNSPSC 41181522 Properdin factor B immunological test system is a Commodity code that does not align with the recent state and local procurement activity posted under it. The recent opportunities tagged to this code include optical surface profilometers, airfield photometric testing systems, drug discovery software suites, electric meter test boards, high-voltage capacitance measurement modules, process instrumentation and SCADA components, laboratory analyzer repair and maintenance, atmospheric hazard monitoring instruments, nanoindentation equipment, brake testers, laboratory testing and phlebotomy services, spectrophotometers, transformer oil analysis services, landscape architectural services, and analytical system support agreements—none of which fall within the scope of immunological test systems or properdin factor B diagnostics. The mismatch between the code's nominal scope and the actual goods and services posted suggests either systematic tagging errors in the procurement system or that this code is not actively used for state and local purchasing in its intended category.

The recent opportunities are drawn from health departments, utilities, educational institutions, transportation authorities, and municipal governments across Florida, Texas, Colorado, Oregon, and other states, reflecting procurement offices' use of this code for unrelated laboratory and testing equipment acquisitions. No solicitations for actual properdin factor B immunological test systems, diagnostic reagents, or related clinical laboratory consumables appear in the recent activity block. State and local procurement professionals should verify the correct UNSPSC classification for immunological testing products before pursuing opportunities tagged to this code, as current activity suggests it is being used as a default classification for diverse laboratory and measurement equipment rather than for the immunological diagnostics its name describes.
